High temperature resistance magnetic type temperature measuring sensor

Abstract

The invention provides a high temperature resistance magnetic type temperature measuring sensor which comprises a base. An asbestos gasket and a strong-magnetic high temperature resistance magnet arearranged in the base. A copper thin film sensing structure penetrates through the base from bottom to top, and the top of the base is connected with the bottom of a sensor body. The copper thin film sensing structure is connected with the sensor body, and the top of the sensor body is inserted into the bottom end of a stainless steel tube. The stainless steel tube is internally filled with a heatconduction material component, an insulating material component, a heat insulation material component and a waterproof material component. The top end of the stainless steel tube is sealed through a blanking cap, one end of a compensation lead wire is connected with the sensor body, and the other end of the compensation lead wire penetrates through the stainless steel tube and the blanking cap. The high temperature resistance magnetic type temperature measuring sensor is quick in heat conduction, high in measuring precision, rapid in data reaction, capable of achieving real-time on-line measuring, stable in operation, and capable of not being affected by the environment, has the waterproof function, is easy to mount, quick in moving, accurate in measurement and convenient and quick to use,lowers labor cost and resource waste, and guarantees operation of safety production.

Description

technical field [0001] The invention relates to the field of metallurgical technology, in particular to a high temperature resistant magnetic suction temperature measuring sensor. Background technique [0002] At present, the continuous casting process has been widely promoted in the metallurgical industry. During the production process of the tundish car of the continuous casting machine, most of the bottom and wall of the tundish are in the shielded area, and the area behind the crystallizer belongs to the radiation area of ​​the radiation source. The production process post Personnel cannot manually measure the cladding temperature continuously, and when the refractory material is abnormal, it is easy to cause a leakage accident if it cannot be found in time. Once a bag leakage accident occurs, it will cause damage to the equipment, directly cause economic losses, and endanger the personal safety of the personnel at the post. In order to avoid accidents, it is necessary ...
